dc.description.abstractBACKGROUND There is growing interest in the use of information communication technologies to treat obesity An intervention delivered by smartphone could be a convenient potentially cost effective and wide reaching weight management strategy Although there have been studies of texting based interventions and smartphone applications apps used as adjuncts to other treatments there are currently no randomized controlled trials RCT of a stand alone smartphone application for weight loss that focuses primarily on self monitoring of diet and physical activity OBJECTIVE The aim of this pilot study was to collect acceptability and feasibility outcomes of a self monitoring weight management intervention delivered by a smartphone app compared to a website and paper diary METHODS A sample of 128 overweight volunteers were randomized to receive a weight management intervention delivered by smartphone app website or paper diary The smartphone app intervention My Meal Mate MMM was developed by the research team using an evidence based behavioral approach The app incorporates goal setting self monitoring of diet and activity and feedback via weekly text message The website group used an existing commercially available slimming website from a company called Weight Loss Resources who also provided the paper diaries The comparator groups delivered a similar self monitoring intervention to the app but by different modes of delivery Participants were recruited by email intranet newsletters and posters from large local employers Trial duration was 6 months The intervention and comparator groups were self directed with no ongoing human input from the research team The only face to face components were at baseline enrollment and brief follow up sessions at 6 weeks and 6 months to take anthropometric measures and administer questionnaires RESULTS Trial retention was 40 43 93 in the smartphone group 19 42 55 in the website group and 20 43 53 in the diary group at 6 months Adherence was statistically significantly higher in the smartphone group with a mean of 92 days SD 67 of dietary recording compared with 35 days SD 44 in the website group and 29 days SD 39 in the diary group PUnder 001 Self monitoring declined over time in all groups In an intention to treat analysis using baseline observation carried forward for missing data mean weight change at 6 months was 4 6 kg 95 CI 6 2 to 3 0 in the smartphone app group 2 9 kg 95 CI 4 7 to 1 1 in the diary group and 1 3 kg 95 CI 2 7 to 0 1 in the website group BMI change at 6 months was 1 6 kg m 2 95 CI 2 2 to 1 1 in the smartphone group 1 0 kg m 2 95 CI 1 6 to 0 4 in the diary group and 0 5 kg m 2 95 CI 0 9 to 0 0 in the website group Change in body fat was 1 3 95 CI 1 7 to 0 8 in the smartphone group 0 9 95 CI 1 5 to 0 4 in the diary group and 0 5 95 CI 0 9 to 0 0 in the website group CONCLUSIONS The MMM app is an acceptable and feasible weight loss intervention and a full RCT of this approach is warranted TRIAL REGISTRATION ClinicalTrials gov NCT01744535 http clinicaltrials gov ct2 show NCT01744535 Archived by WebCite at http www webcitation org 6FEtc3PVB
